'Our strategy focuses on hydrogen as the long-term solution. We will therefore continue to take an active approach in developing the use of hydrogen fuel. But in technological terms, our path toward hydrogen starts with natural gas,' he said. 'The fuel cell, particularly for reasons of cost, only fits into our energy philosophy where it makes sense - as a chemical 'power station' generating electricity, where it can run auxiliary heating or air conditioning when the engine is switched off.
'But despite all our efforts to develop the use of hydrogen as automotive fuel, we alone are not able to give this highly innovative technology the breakthrough it deserves; the prerequisite is the economic recovery of hydrogen as well as the introduction and implementation of the infrastructure,' he said.
